Recently　Ajax　and　Web　Services　are　hot　technologies　in　computer　field.　We　can　integrate　them　to　build　the　web　application　that　will　be　operated　fluently,　on-demand　and　easy　for　reuse.　This　paper　at　first　introduces　Ajax　and　Web　Services　shortly,　then　analyzes　the　popular　integrated　framework,　in　which　Web　Browsers　access　Web　Services　directly,　and　points　out　the　defects　of　the　framework.　After　that,　this　paper　proposes　a　new　integrated　framework　based　on　duplicate　proxy　pattern,　in　which　Web　Servers　access　Web　Services,　takes　the　project　named　＇AHP　Tool＇　as　an　example　of　the　application　of　it,　and　summarizes　the　advantages　and　disadvantages　of　it　at　the　end.　©2007　IEEE.
